UPA1E102MPD

The UPA1E102MPD from Nichicon is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can (UPA series). It delivers 1000 µF capacitance at 25 V in a compact φ10 × 25 mm package with 5 mm lead spacing for through‑hole mounting.

Designed for applications that require low impedance and high ripple handling, this part is targeted at switching power supplies and general-purpose power‑filtering roles where long life and stable performance at elevated temperature are required.

Key Features

• Capacitance & voltage: 1000 µF nominal capacitance at a rated voltage of 25 V with a tolerance of ±20% (–20%~20%).
• Low impedance: Specified impedance of 66 mΩ supports low‑loss filtering and fast transient response in power circuits.
• High ripple capability: Rated ripple current of 1.26 A at 120 Hz (low frequency) and 1.68 A at 10 kHz (high frequency) for effective smoothing in switching environments.
• Loss tangent (tan δ): tanδ = 0.14 measured at 20°C, 120 Hz, helping quantify dissipation for thermal and stability assessments.
• Wide temperature and endurance: Operating range –55°C to +105°C with an endurance (life) of 4000 hours at 105°C.
• Mechanical and packaging: Radial lead configuration, φ10 × 25 mm can, 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing; part is in mass production.
• Compliance: RoHS‑compliant.

Typical Applications

• Switching Power Supplies: Low impedance and high ripple current ratings make this capacitor suitable for output filtering and bulk energy storage in switching regulators.
• DC‑DC Converters and Power Modules: Compact φ10 × 25 mm package provides capacitance density for board-level power filtering in compact converter designs.
• Industrial Power Electronics: Extended temperature range (–55°C to +105°C) and 4000 h endurance at 105°C support sustained operation in industrial control and power subsystems.
• General Purpose Power Filtering: Through‑hole radial lead format simplifies prototyping and repair while delivering stable capacitance for general power‑supply decoupling.

Unique Advantages

• High ripple handling capability: Explicit ripple ratings at both low (1.26 A @120 Hz) and high frequency (1.68 A @10 kHz) enable designers to size capacitors against real converter stress.
• Low measured impedance (66 mΩ): Reduces voltage ripple and power dissipation in filtering applications, improving regulator stability and thermal headroom.
• Compact radial can: φ10 × 25 mm footprint and 5 mm lead spacing deliver a small PCB footprint while retaining through‑hole mounting robustness.
• Long high‑temperature endurance: 4000 hours at 105°C provides predictable lifetime behavior for designs operating at elevated temperatures.
• Quantified dissipation: Tan δ of 0.14 (20°C, 120 Hz) gives a measurable parameter for loss budgeting and thermal design.
• Production availability: Listed as mass production and offered in bulk/bag packaging for volume procurement and assembly workflows.
